Abstract:
Provided is an interlayer film for laminated glass capable of suppressing the discoloration by the light and heat in an interlayer film including a resin layer colored with a coloring agent. The interlayer film for laminated glass according to the present invention has an infrared reflective layer, and a first resin layer containing a thermoplastic resin, the first resin layer is arranged on a first surface side of the infrared reflective layer, the infrared reflective layer has a first maximum reflection wavelength at a wavelength of 350 nm to 450 nm, and a second maximum reflection wavelength at a wavelength of 800 nm or more, each of reflectance at the first maximum reflection wavelength and reflectance at the second maximum reflection wavelength is 15% or more, and the first resin layer contains a coloring agent.
